Abstract

We study how to achieve, manipulate, and switch classical or quantum nonreciprocal effects of light with a spinning Kerr resonator. In particular, we show that even when there is no classical nonreciprocity (i.e., with the same mean number of photons for both clockwise and counterclockwise propagating modes), it is still possible to realize nonreciprocity of quantum correlations of photons in such a device. Also, by tuning the angular velocity and the optical backscattering strength, higher-order quantum nonreciprocity can appear, featuring qualitatively different third-order optical correlations, even in the absence of any nonreciprocity for both the mean photon number and its second-order correlations. The possibility to switch a single device between a classical isolator and a purely quantum directional system can provide more functions for nonreciprocal materials and new opportunities to realize novel quantum effects and applications, such as nonreciprocal multi-photon blockade, one-way photon bundles, and backaction-immune quantum communications.

Nonreciprocal Photon Blockade

Ran Huang, Adam Miranowicz, Jie‐Qiao Liao +2 more

We propose how to create and manipulate one-way nonclassical light via photon blockade in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB). Specifically, we show that in a spinning Kerr resonator, PB happens when the resonator is driven in one direction but not the other. This occurs because of the Fizeau drag, leading to a full split of the resonance frequencies of the countercirculating modes. Different types of purely quantum correlations, such as single- and two-photon blockades, can emerge in different directions in a well-controlled manner, and the transition from PB to photon-induced tunneling is revealed as well. Our work opens up a new route to achieve quantum nonreciprocal devices, which are crucial elements in chiral quantum technologies or topological photonics.

Nonreciprocal Optomechanical Entanglement against Backscattering Losses

Ya‐Feng Jiao, Sheng-Dian Zhang, Yan‐Lei Zhang +3 more

We propose how to achieve nonreciprocal quantum entanglement of light and motion and reveal its counterintuitive robustness against random losses. We find that by splitting the counterpropagating lights of a spinning resonator via the Sagnac effect, photons and phonons can be entangled strongly in a chosen direction but fully uncorrelated in the other. This makes it possible both to realize quantum nonreciprocity even in the absence of any classical nonreciprocity and also to achieve significant entanglement revival against backscattering losses in practical devices. Our work provides a way to protect and engineer quantum resources by utilizing diverse nonreciprocal devices, for building noise-tolerant quantum processors, realizing chiral networks, and backaction-immune quantum sensors.

Backscattering-Immune Nonreciprocal Optical Solitons in a Spinning Resonator

Bai‐Jun Li, Şahin Kaya Özdemir, Xun‐Wei Xu +2 more

We show that nonreciprocal optical solitons that are immune to backscattering-induced losses appear in a spinning optical Kerr resonator. Nonreciprocity in this device results from the Sagnac-Fiezau drag effect, which is different for pump fields propagating in the spinning direction or in the direction opposite to it. We find that these nonreciprocal solitons are more robust against backscattering losses if the spinning speed of the resonator is properly set. Our work represents a stable nonreciprocal soliton device and provides a promising technique for one-way soliton isolators and lasers, backaction-immmune soliton communication, and enhanced soliton-comb metrology.

Nonreciprocal Quantum Entanglement Against Backscattering

Ya‐Feng Jiao, Sheng-Dian Zhang, Yan‐Lei Zhang +3 more

We propose how to achieve nonreciprocal light-sound entanglement in a spinning resonator and maintain its quality against backscattering losses. We find that by splitting the counter-propagating lights of the resonator via the Sagnac effect, quantum entanglement can be created from one side while prohibited from the other, and it is possible to switch such a single device between a classical isolator and a purely quantum diode. Particularly, in the presence of backscattering due to material imperfections in practical devices, significant entanglement revival can be achieved in a highly asymmetric way. This reveals a new strategy to protect quantum resources by engineering nonreciprocal devices, for building noise-tolerant quantum processors, realizing chiral networks, and invisible quantum sensing.

Nonreciprocal photon blockade and directional amplification in a spinning resonator coupled to a two-level atom

Yu-Wei Jing, Hai-Quan Shi, Xun‐Wei Xu

We propose a scheme to realize nonreciprocal photon blockade and directional amplification in a spinning resonator with clockwise and counterclockwise traveling modes coupled to a stationary two-level atom. By manipulating the rotational frequency of the resonator, the two-level atom can be resonant with one of the traveling modes and largely detuned from the other one. Nonreciprocal conventional photon blockade is induced by the difference of the detunings between the two-level atom and the optical modes traveling in different directions. Besides that, nonreciprocal unconventional photon blockade (UPB) based on the quantum interference can also be observed in the system. Based on the mechanism for nonreciprocal UPB, directional amplification of the blockaded photons is predicted by driving the spinning resonator and stationary two-level atom simultaneously. Our proposal will be applicable to achieve highly efficient nonreciprocal single-photon devices for applications in chiral quantum information processing.
